SPECIFICATION forming part of Letters Patent No. 355,541, dated January 4, 1887.

Application led September -20, 1886. Serial No. 214,019. (No model.) v v To all whom it witty concern:

Be it known that I, TARGE G. MANDT, a citizen of the United States, and a resident .of Stoughton, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in Vehicle-Tongues; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make'and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a perspective viewqof the for- Ward portion of the running-gear, ofa vehicle, showing my improved tongue. Fig. 2 isasimilar view of the outer portion of the tongue seen from below. Fig. 8 isa longitudinalsectional view of the same. Fig. 4 is a crosssection on linemw, Fig. 3; and Fig. 5 is a similar view on lineyy, Fig 3.

Similar letters of reference indicate corresponding parts in all the figures.

My invention has relation to tubular poles or thills for vehicles; and it consists in the improved construction of parts of such apole or thill and in the improved method of forming it, as hereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the body of the tubular pole, which is made from a tube of wrought iron or steel, the original tube being of the same diameter at all points. This tube is formed with an inwardlyprojecting crease, B, at thel outer portion of the pole, the crease increasing in depth toward the end of the pole, `causing that end of the pole to be tapering towardthe end.

The stop C for the neck-yoke is preferably secured with its ends in the groove formed by the crease i n the under side of the tongue by means of suitable bolts.

` The crease or creases may be formed when the tube is heated by means of suitable dies or rollers,or it may be formed by simply hammering the crease in the heated metal and afterward rounding the tapered portion. It follows that the pole or rod may be used as a vehicletongue, as a thill, as a tongue for agricultural machines, or for any purpose where a tubular poleior rod is to be used with a tapering end, this method of tapering a tube being simple and cheap and requiring very little machinery to be accomplished.

Having thus described my invention,I claim and desire to secure by Letters Patent ofthe United Statesl. A. tubular pole having its tapering end formed with a longitudinal inward crease or creases of increasing depth toward the end, as

3. Ihe improved method of tapering tubular poles, consisting in forming a longitudinal crease 1n the portion l'toloe tapered, increasing in depth toward the end, as alndfor the pur-v pose shown and set forth. A

In testimony that I claim thek foregoing as my own I have hereunto affixed my signature
